Theming the Event Module

Hello,

I'm pretty new to Drupal, especially theming. I am working on a site that I added the Event module to. I love how it works, it does exactly what I need it to do. But when I'm on my main calendar page, there are two things I''m looking to change. At the top are two dropdown menus that (1) "Select event terms to filter by" and (2) "Select event type to filter by". I want to change the theme so that the second dropdown doesn't even appear.

Then I'm looking to change the vertical list of "week day list table" that changes the calendar view to be a horizontal list. I was hoping it was going to be as easy as changing some css, but its not working for me. Any help by instructions or just a wave in the right direction would be greatly appreciated.

Thanks so much in advance!
